Jason Newstead's Tone

Im a big Metallica fan from their old "Ride the Lightning & Master of Puppets Days" and I just picked up their Cunning Stunts DVD the other day. Any way, the real question is what or how does one achieve Jason Newsteads sound on songs like: Aint my biatch, King Nothing, One, and Wherever I may Roam. Those were the songs in which I felt that particulary crunchy tone was most prevalent. I appreciate any help that is given. Unfotunatley, I am also expecting many posts telling me I should find my own tone and not to copy anothers, but too bad. I really dig this tone and want to replicate and experiemt with it very badly.

A little note about his playing technique. I read an article by him in Bass Player with him explaining his picking techniques. He uses a 1.00 MM Triangle, clasped between his middle and index finger and his thumb, with his pinky holding to the bottom strings for stability and he palm mutes his bass. Go figure.

His tone on the new Voivod album is very good. IMO much better than the Metallica stuff. Maybe it's because he can do what he likes now that he's out of Metallica. The Sadowsky has a lot to do with his tone though.
